This is an ALPHA code for experimental purposes.

Improves NN (and system) performance by up to 60% in some cases, when there is high system load. For example when 4k RGB + 800p enabled in 26_1_spatial_mobilenet.py we gain +9 fps (15 vs 24), CPU load: -20% LRT (57 vs 37), +6% (62 vs 69) LOS.

In more simple cases, for example 08_rgb_mobilenet.py the NN is 13-15% faster.

Known issues:
Stereo subpixel mode doesn't work properly.

Feel free to report other issues too.
